Application March 29, 1950, Serial No. 152,589

8 Claims.

f 1 This invention relates to curb inlets for catch basins of the type shown in my prior Patent No. 2,473,279, issued June 14, 1949.

The general object of the curb inlet ofthe said patent and of this application is to provide L a curb inlet casting which will integrally unite the side walls of the catch basin and the sidewalk slab thereof so that the inlet casting will move therewith as the concrete structure expands and contracts with temperature changes and will remain fixedly bonded thereto, and so that the curb inlet casting itself will not move relatively to the wall and roof structure of the catch basin under said temperature changes.

In the aforesaid patent, these ends are achieved by providing the end walls of the inlet casting with a pair of protuberances extending outwardly and generally longitudinally of the casting and which present a vertical dimension substantially centered at the juncture of the side walls of the catchy basin and the sidewalk slab thereof, with the lower portions of the protuberances embedded in the side walls and with the upper portions of the protuberances embedded in said sidewalk slab.

One of the objects of the present invention is to provide a curb inlet casting as described above, inv which the, said protuberances have modified and improved or alternative constructions.

Another object is to provide a curb inlet casting as described, implemented with means of additionally tying or securing the casting to adjacent structures such as the catch basin, the sidewalk slab, or the gutter grating.

For the attainment of the foregoing and such other objects of invention as may appear or be pointed out herein, I have shown several forms of my invention in the accompanying drawings, wherein:

Fig. 1 is a perspective view of the curb inlet;

Fig. 2 is an elevational section through the unpaved catch basin and curb inlet casting;

Fig. 3 is a top view, partially in section on the line 3-3 of Fig. 2;

Fig. 4 is a fragmental elevational sectional view (similar to Fig. 2) but showing a modified form;

and l Fig. 5 is a fragmental elevational sectional view, like Fig. 4, showing a modification thereof. The improved curb inlet casting, generally designated I0, comprises a base plate Il and an upper bar I2, between which may be provided a plurality of intermediate partitions I3, integrally united at'their lower portions with base plate II improved 2 and at their upper portions with longitudinal bar I2. Intermediate partitions I3, ofwhich live are shown in Fig. l, for exemplication, provide a plurality of wide openings I5 in front of the casting.

The partitions I3, as best seen in Figs.'1 and 2, are shown as of irregular triangular shape with the base thereof at the front of the casting and with their apices I1 rearwardly disposed. These partitions are shown in the drawings as equally spaced from each other and from the end walls, I4, I4, of the casting.

Projecting longitudinally outwardly of the end walls i4, I4 are a vertically disposed flange or protuberance 20 and a horizontally disposed flange or protuberance 2I`. The vertical protuberance 20 is shown as located substantially at the medial vertical plane through end wall I4, Fig. 1 (see also Fig. 2) and the horizontal protuberance 2| is shown as located substantially at the medial horizontal plane therethrough. Horizontal protuberance 2l is shownY as normal to the vertical one 20 and as extending rearwardly therefrom and as substantially coplanar to the medial horizontal plane through the apex I1 of the end wall.

The protuberances 2l, 2l are sodisposed and dimensioned that the lower portions thereof are embedded in the side walls 9, 9 of the catch basin, see Figs. 4-5, and the upper portions thereof are embedded in the sidewalk slab 6.

The base II of the improved curb inlet casting is disposed at the top surface of front wall 2 of the catch basin, this being substantially level with the subgrade 3, which is stepped down from the level of sidewalk slab 6. The aforesaid front bar I2 of the improved curb casting constitutes the curb at the sidewalk stepdown. The aforesaid sub-grade 3 1s further depressed below the roadway level 5 to form a gutter, which is covered by the gutter grating 4.

The front of the catch-basin (where the curb inlet casting is placed) is completed by a front wall 2 of concrete, which is integrally united, see Fig. 3, with the side walls 3, 9. As best shown in Fig. 2, the front wall 2 does not unite with the sidewalk slab Ii but presents its top surface spaced a short distance below the sidewall; slab. After the side walls 9, 9 of the catch basin and its front wall 2 are poured, the inlet casting Iii is placed in position along the front of the basin, with the base plate l i of the casting resting upon the aforesaid top surface of front wall 2. Thereafter, the sidewalk-slab 6 is poured, to unite the casing in place.

As a resultl of the embedding of the protuberances 20, 2| in the side walls and sidewalk slab of the catch basin as described above, these and the front wall of the catch basin are integrally united together, so that all parts of the catch basin expand and contract together. Additionally, the curb inlet casting is bonded thereto andl is prevented from moving relative to the catch basin.

The horizontal protuberance 2l' may be provided with an'aperture- 23, and the base plate il may be provided with an aperture I9, positioned preferably near the end walls I4, i4. The apertures 23, I9 serve to increase the eiect-veness of the bonding of the curb inlet casting to the catch basin and the sidewalk slab. llhey mayalso serve to additionally bond theJ cunb; inlet casting to the adjacent structures in the manner shown in Figs. 4 and 5. The curb inlet casting may beA tied in with the reinforcing rods 6X of the sidewalk slab as shownilfis. 4Jv as oir/means; of oonnootinerods 24V en as; formed at; its nlorer ond into onools. 215;,- ,wlnolils slipped-about; ono of tho reinforcing rods..
